Title: A reversing device for the drive of a travelling inked ribbon, especially in franking machines
IPC: B41J33/516
Filed: 1959-09-16
Abstract: 917,562. Ink-ribbon mechanisms. AGFA A.G. Sept. 16, 1959 [Sept. 22, 1958], No. 31641/59. Class 100 (4). An ink-ribbon feed mechanism particularly for a franking machine has an automatic reversing mechanism controlled by an overcentre spring. A double pawl 8 is pivoted at 9a on a counterbalanced member 9, in turn pivoted at 9b on a rocker 11 capable of racking on a pin 11b, and is arranged to engage one of the ratchet wheels 6, 7 to effect feeding of an inkribbon 3 between spools 1, 2. Springs 10, 12 control the position of the pawl 8 and the member 9 respectively while a spring 15 tends to hold the rocker 11 against a stop 14. In operation of the franking machine a pin 11c is engaged to move the rocker 11 against a stop 13 and in the position of the pawl 8 shown to cause a feed stroke of the ratchet wheel 6. When the spool 2 is exhausted resistance to a feed stroke by the ratchet wheel 6 causes the pawl 8 to rock the counterbalanced member 9 against the force of the spring 12 and past its dead centre position until the member is arrested by a stop 11d and the spring 10 forces the pawl into engagement with the other ratchet wheel 7 to reverse the ribbon feed direction. Coil springs 16, 17 resists reverse movement of the ratchet wheels 6, 7 after a feed stroke but do not resist such a feed stroke. The feed stroke of the pawl 8 is not equal to an exact number of teeth on the ratchet wheel so that feed reversal usually requires two strokes to be effective and a different part of the ribbon is used after each reversal thus ensuring maximum wear.

Abstract: 392,949. Resilient engine-mountings. TROTT, R. S., 704, Equitable Building, Denver, Colorado, U.S.A. Nov. 16, 1931, No. 31670. [Class 79 (iii).] To eliminate vibration or tremor due to engine torque reactions in motor vehicles, aircraft and marine vessels, substantially the whole of the weight of the power unit is pivotally supported on a frame by a pair of longitudinally spaced mountings one at least of which is of non-metallic resilient material permitting an orbital movement of the unit with reference to the frame. The mountings may be concentric with the crank shaft or vertically or laterally spaced therefrom according to the balance of the engine or whether it is desired to use part of the weight of the engine to oppose or augment the torque reaction effects. To damp or cushion the reactions the unit is connected to one or both side frame members through rubber cushions with or without progressively increasing resistance, conical or helical coil springs, hydraulic or pneumatic devices or by combinations of such means. The power unit may or may not include the change-speed gear on a motor vehicle, the propeller on aircraft or the reversing gear &c. on marine craft. The engine and gear-box unit 1 on a motor vehicle, Fig. 1, is supported at the ends on cross-frame members 4, 5 by mountings 2, 3 one or both of which are sufficiently resilent to allow movements of the unit of an orbital nature about an axis coinciding with or intersecting the crank shaft axis. The mountings may comprise rubber blocks, as shown in Fig. 2, or rubber journal bearings, as shown in Fig. 3. One end mounting may be only sufficiently resilient to permit orbital movement at the other end of the unit and may be of wood or like material or may comprise a ball or roller or plain pivotal bearing. The torque cushioning connections 8 or 9, Fig. 1, may be of the form shown in Fig. 2. The torque connections may be so set as to place additional load upon the pivotal mountings.
